The Investigation

"Our Constitutional Duty is Clear"

In this episode of The Investigation, presidential candidate and US Rep. Seth Moulton (D-MA) talks about why he's ratcheting up calls for Trump's impeachment, even though it continues to be a contentious topic with his colleagues in the House and fellow 2020 contenders. "We spend too much time in this party debating the politics of impeachment, when the law is very clear and our constitutional duty is clear," Moulton says, explaining why he thinks that skimming over the topic in the lead up to the general election would be "a mistake," and why he believes that Robert Mueller's pending appearance on Capitol Hill could be a game changer. Later, the ABC team forecasts what to expect from Mueller's testimony and analyzes the political roadblocks facing congressional democrats who want to launch impeachment proceedings against Trump. <p>Learn more about your ad choices.

It's one of the rarest political events in American history, one that only three presidents have ever experienced before today. Just months after the release of Special Counsel Robert Mueller's report, the White House finds itself under fire from a new front: an impeachment inquiry.  Who was on that July 25th call between President Trump and President Zelensky? What was promised and who was pressured? And how has that one phone call raised the question, once again, of possible foreign intervention in U.S. elections and "quid pro quo" demands to other foreign leaders?  We'll bring you all of our exclusive reporting -- from the halls of Capitol Hill to Maiden Square in Kyiv.  Along the way, you'll get insight from legal analysts and historians, politicians and principals -- those who are driving the developments in this rapidly-unfolding story -- all as we count down the days until an impeachment vote and a possible senate trial.
